I am working to build an out-of-tree module in GNURADIO 3.7.3 on UBUNTU  
14.10 OS. While building a module using command “cmake …/”, i am facing  
an error which is stated as follows:

spitprojectlab-OptiPlex-3010:~/gr-howto/build$ cmake …/  
– Build type not specified: defaulting to release.  
– Boost version: 1.55.0  
– Found the following Boost libraries:  
– filesystem  
– system  
CMake Error at CMakeLists.txt:93 (find\_package):  
By not providing “FindGnuradio.cmake” in CMAKE\_MODULE\_PATH this  
project has  
asked CMake to find a package configuration file provided by  
“Gnuradio”,  
but CMake did not find one.

Could not find a package configuration file provided by “Gnuradio”  
(requested version 3.7.3) with any of the following names:

```
GnuradioConfig.cmake
gnuradio-config.cmake

```

Add the installation prefix of “Gnuradio” to CMAKE\_PREFIX\_PATH or set  
“Gnuradio\_DIR” to a directory containing one of the above files. If  
“Gnuradio” provides a separate development package or SDK, be sure it  
has  
been installed.

– Configuring incomplete, errors occurred!

Any guidance would be much appreciated

Thank you in advance
